A dress dubbed "Herself" is the first prototype dreamed up by Catalytic Clothing — a collaborative effort between the London College of Fashion, the University of Sheffield and the University of Ulster. The dress is coated with a special concrete mixture that uses sunlight to facilitate a reaction between titanium dioxide on the surface of the fabric and pollutants in the air. In other words, the dress can absorb nitrogen dioxide and carbon monoxide while you walk around looking good. Just imagine — if products like this actually end up on the market, fashion and excessive vanity might actually be environmentally heroic. Los Angeles will be saved!

Baby Bjorns have never been much of a fashion statement, but looking good isn't quite as important when you need to tote a child around. Using a similar harness to prop up your iPad is another matter altogether. Having a flat surface to use with your iPad at all times might be more convenient, but you'll need to be pretty comfortable with the idea of looking completely ridiculous in public. Then again, it's probably better than wearing a dress with a giant iPod pocket. $130 - Assero via Fashionably Geek

In honor of the recent movie "Tron: Legacy," designer Edmundo Castillo created Light Sandals that feature the same electroluminescent material used in the film's costumes. On the plus side, you won't need to worry about being mowed down by motorists while drunkenly wandering the streets after a party. On the downside, you can't plug your iPhone into your shoe for a quick charge. That doesn't seem like too much to ask for the $1,650 asking price. Edmundo Castillo via Fashionably Geek

If you are a man with even the slightest concern about cell phone radiation, the ability to store your iPhone in your underwear might be less than desirable — maybe even downright terrifying. That having been said, SeV Travel Boxers feature an iPhone-sized pocket and anti-microbial fabric. That's definitely a plus because you don't want underwear microbes all over your phone. Just to be safe, when wearing a pair, you should probably stick to the speakerphone or a Bluetooth headset. $20 - ScotteVest via Fashionably Geek

If you don't have enough money for real musical instruments, the next best thing would be to start a band using ThinkGeek's instrument shirts. Choose from guitar, drums and synthesizer. Each shirt features a fully playable electronic instrument on the front and an internal speaker or belt-mounted amp to boost the sound. Plus, the electronics are easily removed for washing. You'll be on your way to stardom in no time — though in this situation, groupies tearing off your clothes might actually be a problem. $29.99 - ThinkGeek via Fashionably Geek

The potential for the tiny iPod Nano to be used as a watch was immediately apparent, so companies scrambled to release their own compatible watchbands. Many of these bands are less than stellar. (I mean, let's leave snap bracelets in the '80s where they belong.) But others work. HEX has released a line of simple but colorful silicone watchbands for the iPod Nano and they have a sport band on the way that features a slot for a Nike+ dongle that can be used to electronically track your workouts. $29.99 - HEX via Fashionably Geek

Scrolling LED belt buckle

Let your belt buckle do the talking for you. This scrolling display features 147 LEDs and memory for six programmable messages up to 256 characters long. It's not what I would call "subtle" or even "tasteful," but hey, at least it doesn't stream your tweets or show stock quotes. Not yet, anyway. $19.99 to $32.99 - Think Geek

Here's a solution to travelers who are sensitive about the TSA's full-body scanners. This line of underwear for men, women and kids features the text of the Fourth Amendment — the one that forbids unreasonable search and seizure — strategically printed in metallic ink. It covers up nudity but shows up easily on X-ray scanners so you can make a statement about your constitutional rights. Of course, wearing this sort of thing might single you out for "special attention," too. $24 to $45 - 4th Amendment Wear via Fashionably Geek

I'm blind as a bat. I can see fine up close but from a distance I can't tell the difference between an 18-wheeler and a husky gentleman riding a bike. And the sad thing is that it's only going to get worse. I imagine that it won't be long before I'll need reading glasses or bifocals, which is why I'm excited about what PixelOptics is doing with eyewear. Their emPower glasses utilize an LCD layer that can be refocused electronically with a swipe of the finger. They're slated for release in April starting at $1,200. Pricey, but it's still cheaper than Lasik. PixelOptics

Fluid dress

Take 600 feet of tubing, run dyed water through it, and then control the flow with a computerized backpack pump. That's what designer Charlie Bucket did to create the Fluid Dress, a fashion phenomenon whose crazy patterns have to be watched in full video (above) to be believed. It's probably not the kind of thing that the average woman would wear, but I'm sure Lady Gaga would risk a hernia to wear it. Casual Profanity via Fashionably Geek
